Hello,
I've had an unfortunate string recently with email accounts being hijacked by spammers and used to relay spam through my server. I don't know if the spammers are getting the email through malware on the PC of the account owner, sniffing wifi connections, or offering chocolate bars to the users, but it's happened 3 times in about 6 months.
In any event, I noticed that in each case the spammers are using a completely fake from address - usually @aol.com or some other big name domain.
It seems to me that I should not be allowing email to be sent through my server where the domain in the from address is not a local domain or some domain that I explicitly allow. Is there an option to enable this kind of restriction?
It would be even nicer if I had the option to limit authenticated senders to only sending from the address they authenticated with. So, if I auth with the name "[email protected]", I can only send email where my from address is "jerr[email protected]". Is there a reasonable way to do this?
Thanks much!
Jerry
